11 Unbolt the exhaust downpipe from the
manifold by unscrewing the flange bolts. Support
the exhaust pipe by tying it up with wire.

12 Release the alternator mounting and
adjuster link bolts, push the alternator in
towards the engine and slip the drivebelt from
the pulleys.

13 Unbolt and remove the timing belt cover
(upper cover only on later models).

14 Slacken the belt tensioner bolts, lever the
tensioner to one side against the pressure of
the coil spring (if fitted) and retighten the bolts.

15 With the timing belt now slack, slip it from
the camshaft sprocket.

16 Disconnect the leads from the spark plugs
and unscrew and remove the spark plugs.

17 Remove the rocker cover.

18 Unscrew the cylinder head bolts,
progressively and in the sequence shown
(see illustration). Discard the bolts, as new
ones must be used at reassembly.

7.18 Cylinder head bolt removal sequence

19 Remove the cylinder head and manifolds.

Refitting
20 Before installing the cylinder head, make
sure that the mating surfaces of head and
block are perfectly clean with the head
locating dowels in position. Clean the bolt
holes free from oil. In extreme cases it is
possible for oil left in the holes to crack the
block due to hydraulic pressure.

21 Turn the crankshaft to position No 1 piston
about 20 mm (0.8 in) before it reaches TDC.

22 Place a new gasket on the cylinder block
and then locate the cylinder head on its
dowels. The upper surface of the gasket is
marked OBEN-TOP (see illustration).

7.22 The upper surface of the cylinder head gasket is marked OBEN-TOP
(arrowed)

23 Install and tighten the new cylinder head
bolts, tightening them in four stages (see
Specifications). After the first two stages, the
bolt heads should be marked with a spot of
quick-drying paint so that the paint spots all
face the same direction. Now tighten the bolts
(Stage 3) through 90° (quarter turn) followed
by a further 90° (Stage 4). Tighten the bolts at
each stage only in the sequence shown
before going on to the next stage. If all the
bolts have been tightened equally, the paint
spots should now all be pointing in the same
direction (see illustrations).

7.23b Tightening the cylinder head bolts

24 Fit the timing belt (Section 4).

25 Refitting and reconnection of all other
components is a reversal of dismantling, with
reference to the relevant Chapter.

26 Refill the cooling system (Chapter 1).

Fuel injection engines
Note: The cylinder head must only be
removed when the engine is cold. New
cylinder head bolts and a new gasket must be
used on refitting.

33 Relieve the fuel system pressure by slowly
loosening the fuel feed pipe union at the
warm-up regulator (see illustration). Absorb
fuel leakage in a cloth. Reference to the fuelinjection
system layout in Chapter 4, Part B,
or D, as applicable will assist in identification
of the relevant components where necessary.

35 Disconnect the two fuel pipe unions at the
warm-up regulator, the single pipe to the cold
start valve and the four injector feed pipes at
the fuel distributor (see illustration). Recover
the sealing washers located on each side of
the banjo unions and seal all disconnected
pipes and orifices to prevent dirt ingress.

41 Disconnect all relevant hoses, pipes and
wiring to facilitate cylinder head removal, with
reference to the appropriate Sections of
Chapters 4 and 5.

42 Disconnect the throttle cable as described
in Chapter 4, Part C or Part D, as applicable.

43 The remainder of the removal and the
refitting sequence is the same as described
for carburettor engines in paragraphs 11 to 26
inclusive.

RS Turbo models
44 Disconnect the battery negative lead.

45 Drain the cooling system as described in
Chapter 1.

46 Disconnect the inlet air hose and the
connecting hose at the inlet air duct, then
undo the two bolts and remove the air duct
from the rocker cover. Disconnect the sensor
multi plugs (see illustration).

52 Relieve the fuel system pressure by slowly
loosening the cold start valve union on the top
of the fuel distributor (see illustration).

Absorb fuel leakage in a cloth. Reference to
the fuel-injection system layout in Chapter 4,
Part B will assist in identification of the
relevant components where necessary.

7.52 Cold start valve union on fuel distributor - RS Turbo

53 Disconnect the fuel pipes at the fuel
injectors and at the cold start valve (see
illustration). Recover the sealing washers
located on each side of the banjo unions and
seal all disconnected pipes and orifices to
prevent dirt ingress. Move the fuel pipes clear
of the cylinder head.

55 Disconnect the leads from the spark plugs
and remove the distributor cap.

56 The remainder of the removal and the
refitting sequence is the same as described
for carburettor engines in paragraphs 12 to 26
inclusive.
